To store the battery
1. If the scooter will not be used for
more than one month, remove the
battery, fully charge it, and then
place it in a cool, dry place.
2. If the battery will be stored for
more than two months, check the
specific gravity of the electrolyte
at least once a month and fully
charge the battery whenever
necessary.
3. Fully charge the battery before
installation.
4. After installation, make sure that
the battery leads are properly
connected to the battery terminals
and that the breather hose is
properly routed, in good condition,
and not obstructed.
EC000099
If the breather hose is positioned in
such a way that the frame is exposed
to electrolyte or gas expelled from
the battery, the frame could sufferstructural and external damages.
EAU00809
Replacing the fuseThe fuse holder is located beside the
battery compartment behind panel A.
If the fuse is blown, replace it as follows.
1. Turn the key to “
” and turn off
all electrical circuits.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage.
Specified fuse:
7 A
EC000103
Do not use a fuse of a higher
amperage rating than recommended
to avoid causing extensive damage
to the electrical system and possiblya fire.
3. Turn the key to “
” and turn on
the electrical circuits to check if the
devices operate.
4. If the fuse immediately blows
again, have a Yamaha dealer
check the electrical system.
